Definition of Sensation, Attention, and Perception

Subject: Behavioral Science

Overview

Sensation is the process through which we pick up on environmental physical energy and encode brain signals. The brain and spinal cord, as well as different relay stations and processing areas, are connected to each sensory system through a type of channel made up of a sensitive element (receptor) and nerve fibers. In psychology, attention is defined as the focus of consciousness on one phenomena above all other inputs. In a broad sense, perception refers to becoming aware of an object's characteristics, occurrences, and awakening the senses. In order to represent and comprehend the environment, sensory data must be organized, recognized, and interpreted.

Sensation, Attention, and Perception

Sensation

Visual sensation: It starts with the electromagnetic radiation that objects emit or reflect. Visual is the must important of all sensation.

Auditory (hearing),
Olfactory (smell),
Gustation (taste),
Cutaneous (skin),
Kinesthetic (movement).

Attention

Sensation is the mechanism through which humans decode brain impulses and detect physical energy in the surroundings. Each sensory system is linked to the brain and spinal cord, as well as several relay stations and processing regions, through a sort of channel made up of a sensitive element (receptor) and nerve fibers. When a sensory channel is active, we get a sensation that is its characteristic.

Perception

It is a generic phrase for becoming aware of an object's traits, happenings, and awakening the senses. In order to represent and comprehend the environment, sensory data must be organized, recognized, and interpreted. Perception involves several steps: receiving, selecting, organizing, and finally interpreting.

Questions and Answers

Define the term sensation and attention ?

Sensation is the process by which we detect physical energy the environment and encode is neural signs. Each sensory system has a kind of channel consisting of a sensitive element (receptor) nerve fibers leading from the receptors to the brain and spinal cord and various relay station and processing area within a brain. When a sensory channel is stimulated we have a sensation which is characteristics of a channel.

Attention, in psychology, the concentration of awareness on some phenomenon to the exclusion of other stimuli.Attention is awareness of the here and now in a focal and perceptive way. For early psychologists, such as Edward Bradford Titchener, attention determined the content of consciousness and influenced the quality of conscious experience. In subsequent years less emphasis was placed on the subjective element of consciousness and more on the behavior patterns by which attention could be recognized in others.

Define Perception .

It is general terms referring to the awareness of object qualities, events and stimulating the sense organ. It is the organization, identification and interpretation of sensory information in other to represent and understand the environment. There are some steps in perception: first, we receive, second we select, third we organized and fourth we interpret.
